Galaxy Note 3, GearFit Auto-Lock Missing

I have had this Note 3/Gear Fit combo for a couple of months. Loved the auto-lock feature when the Gear Fit was in proximity to the phone. Now, all of a sudden, that option is just... gone! Not only does it no longer work, the option simply isn't there! (I'm on T-Mo). Following is the transcript of my (unedited) live chat with Samsung support (totally unhelpful). Anybody know how to fix this?

I have the same problem with the exact same model number for galaxy gear fit. My note 3 is on Verizon. I had the auto lock feature when I first setup watch, but now the option is gone in the settings on the Galaxy Gear Fit Manager app on my phone. I think the tech was right when they said he thought maybe Samsung upgraded the firmware to leave the auto lock feature off and that there was no way to downgrade it. That is too bad because next to receiving notification the auto lock (and auto unlocking) was the best feature on the Galaxy Gear Fit.
